I received my Tribunus a couple weeks ago. I got it installed in my 550sx just in time for the -40C weather to roll in ....... so no test flights yet.

When I got it, I updated the firmware using the PC interface and while in the interface, changed two selections to the "Vbar" setting and set the BEC voltage. After finishing the heli installation and powering up the VControl and 550sx, there was literally NO further setup to do for the ESC! Even without blades on, the spool up on the bench was soooo smooth and it settled at each of my governor bank speeds when switched. I can't wait to try it in the air.

Also, I removed a YGE120HV w/heatsink, a VBar UI sensor, and a WR Bec.......totalling 340g for the Tribunus which weighed 110g. Nice!

GregCA,
It looks like the cold weather will be here for a while so I may not have any results to post for some time.

I didn't use a fan. At the motor end of the ESC (top), there is very little clearance between the ESC's heatsink and the canopy. 1/8"-1/4" . So no room for a fan there. On the lower end of the ESC, there might be room for a fan, but you may need some extra ventilation in the canopy to make it worthwhile??? I'm trying mine without a fan and see how it goes.

Also for a Neo gov are separating the signal for the rpm sensor out of the cable and using the power feeds into another port?

You can plug the ESC's RPM lead, with its secondary BEC power feed, directly into the NEO's RPM port since it is on the NEO's power bus. This is what I do. On the old mini VBar, you did have to separate the RPM lead and BEC secondary power feed.

Well...hoping the weather tomorrow is nice enough to go try the Tribunus out.

Quick question....... After initially updating the firmware, I set the gov type to Vbar and the communication to vbar and the BEC voltage on the PC, then once the esc was connected on the heli, I powered up the VControl, powered up the heli, went to heli setup - governor and didn't change anything there. ( the main gov settings were also done because it was already flying with a YGE ).

Do I need to do the esc endpoint calibration still? or did the VControl and Tribunus just figure that out themselves when I entered the setup governor screen?

I set mine to VBar governor first and then it said in the VC that it was OK it didn't go through the the automatic setup. So I changed it to a different mode, saved it, powered the esc off and on. Shut the software down and started it again to make sure the new settings had saved. Then powered the esc off. Then powered the VC and the heli went to the governor screen and then it did its automatic setup. I wanted to make sure the VControl would perform the auto setup.

Just to clarify....this method is to reprogram your NEO governor settings? Or the ESC's internal settings? ie: after the "auto setup" runs on the VControl, the governor settings looking at the VControl governor pages (gain, collective add, etc) should be changed?

I saved the mode to built in gov and then back to vbar, but it didn't do any reset of settings that I could notice. I may save the model and just try a completely fresh setup.

From my understanding it sets the esc. If you have been using the Vbar governor then the setting will be the same. For a new setup you will have to do the rpm setting and all.
I put one on a Goblin 420. I know it it over kill but I did not have to buy the U/I sensor so the price was about the same with less work.

Quote: If you equip your heli with a Tribunus Regler from Scorpion , the model setup wizzard will automatically detect and program the Tribunus so it perfectly matches to the programmed model, and uses the VBar´s governor. Just a few clicks will do the whole programming work. It never was easier!

You MUST perform throttle range calibration before the first use
of the ESC, except if you are using external governor mode,
remove propeller/pinion from motor or back o pinion from
main gear while performing initial throttle range calibration.

You only perform throttle range calibration if you are using the internal governor.

Make sure you have saved a non governor mode first. Confirm it in the Scorpion software. You will have to power down the esc and reset / restart the sorftware to see if you have saved the settings in the esc to a different mode. Then when you go to the governor setup you will see the Vcontrol with the dots scrolling (loading) as it is setting up the esc and VControl.
